Q How do the lateral conveying and rotational conveying devices avoid the angle steel from getting stuck or falling during the turning process? How is the daily maintenance carried out?
A The rotational conveying is driven by a reducer. It is necessary to ensure that the surface of the angle steel has no severe warping or welding slag. It is recommended to regularly check the parallelism and rotational flexibility of the conveying rollers, and clean the iron filings on the roller path. The lubricating oil of the reducer should be replaced every six months, and the tension of the chain or synchronous belt should be checked.

Q The shearing unit uses a single-edge shearing method and has no waste. Will there be end deformation or inclined cutting edges when shearing thick angle steel (such as when the thickness is ≥ 10mm)?
A The single-edge shearing force is large. Under normal circumstances, the cutting edge is smooth without waste. However, for angle steel with a thickness close to the upper limit of the equipment, it is recommended to reduce the shearing speed and check if the gap between the blade is adjusted according to the material thickness. If the gap is too large, it is prone to cause slight deformation or burrs.

Q The punching unit can be equipped with three different diameter punches. Is it necessary to re-trim the tool when changing the punch? How is the positioning accuracy of the CNC movement of the molds guaranteed?
A After changing the punch, it is usually necessary to check the concentricity of the mold and make minor adjustments. The CNC movement of the three sets of molds is controlled by the servo system, and is accompanied by feedback from photoelectric encoders. The positioning accuracy can reach within ±0.2mm. It is recommended to regularly calibrate the position of the mold library and clean the punching waste to avoid affecting the movement accuracy.
